Whats is the best spectre?

I'm going to start the next league on necromancer, but i don't know about best spectre. I heard about archers from the map under the redeemer influence. Some build have other spectres. Which is the best in your opinion?

Depends on what you want to do.

If you are new to spectres, I recommend Slave Drivers.

They are good at both clear AND bossing.
They are easily available for leveling, found in act 5 slave pens.

There are better spectres for clearing, there are better spectres for bossing, not sure that are any that do both better, and all such spectres are found in special maps, so not easy to get at first.


Start with Slave Drivers, then maybe later try one of the special map ones.
(Redemption Sentry is the archer one you mentioned, AMAZING clear speed, MASSIVE life pool, but not as much dps as Slave Drivers on bosses.)

P.S.

Should be really good at Harvesting, as I think Vaal Summon Skel will dominate plant battles.
